Directions for Use

Heartgard (Ivermectin) is given
once a month year round for the prevention of heartworm disease. The usual
dose of ivermectin in dogs up to 25 lb is 68mcg - 1 tablet from blue pack, for 26-50 lb is
136mcg - 1 tablet from green pack and for 51-100 lb is 272mcg - 1 tablet from brown
pack. Dogs over 100 lb are given a combination of the tablets.

Cautions

This medication should not be used in animals
allergic to it. Heartworm testing should be performed prior to the start of
prevention therapy. If the animal is off ivermectin for 6 months or less, start
the medication and test after 6 months since microfilaria, which take 6 months
to mature, may result in a positive test result.

Possible Side Effects

The side effects of ivermectin are rare at the recommended dosage. Heartgard
Tablets has a wide margin of safety for all sizes and breeds of dogs. It is
approved for use in puppies as young as 6 weeks, small dogs regardless of
weight, pregnant or breeding bitches, stud dogs, and Collies.
